Figure 7-5 shows that each register access consists of 24 bits. The first bit is high for a read and low for a write.

The next 15 bits are the address of the register that is to be written to. During write operations, the last eight bits are the data written to the addressed register. During read operations, the last eight bits on SDI are ignored, and, during this time, the SDO outputs the data from the addressed register. Figure 7-5 shows the serial protocol details.
